On the red carpet, she told ELLE.com what advice she'd give to her girls—and any other discouraged young woman—after the U.S. election. "Well, they don't understand anything yet so keep your hand out of the cookie jar right now is the advice," Lively started, with a laugh (Lively's eldest daughter James turns two in December). "But you know, just to use your voice. Don't let anybody silence you, ever, and it's about spreading love, you know? Because that's the easy thing to do right now, is to say—women, you get angry or you get upset or you get hurt and you want to lash out, but what we're combatting is hate. So it's about spreading love and using your voice."

Lively herself will continue to be a role model to her kids. "You just have to set an example, you know? It's so important," she said. "In times like this you can either curl up and be really depressed about the state of communities that are underserved, or you can set that example for your children. You just have to figure out how; that's the hardest thing. If somebody just had a playbook and they said, 'this is what do,' but it's about making that extra bit of effort."
